Black Patterns
Black patterns  cause the special Black Gun to have specific behavior. On some
skip timers, this is configurable. On others, the special Black Gun behavior is
fixed to Gun #4. Physical mounting of the black material gun is important when
using this special mode. Refer to the Pattern Preview  area on the Main screen
to see the expected pattern.
The Black Pattern setup is engaged when the Black  mode is enabled on the
Quick Setup  menu (see 4.3.1,  Mode  ).
If your system is equipped with  Carriage Layout
your  Black Patterns  screen will look slightly
different.
There are two Black Pattern modes that can be selected in the setup:
➢ Shadow: Shadow mode applies paint before and/or after the stripe. When the
black gun is in Skip  , the fore shadow/aft shadow lengths will be applied as
entered. When the black gun is in Solid  , it will Gap Fill  (i.e., black paint will be on
for the entire gap between the end of the last stripe and the start of the next).
○ Fore Shadow: The length of black paint to be applied before the beginning of
the stripe.
○ Aft Shadow: The length of black paint to be applied after the end of the stripe.
